Start redocneXk. Open the Windows Task Manager (ctrl+shift+esc). right-click redocneXk.exe and move the mouse to Set Priority. The priority should normally be set to Realtime. I made redocneXk work in Realtime priority because I could not get it not to skip at lower priority. Are you saying that it skips even when it plays on the analog speakers with passthru disabled? If you answer is yes then maybe you have a problem with ASIO. In that case, try to use ASIO in another ASIO app. I suggest you try KRISTAL. In the menu engine, click Preferences... In Audio Setup, make sure 48 kHz is selected. Under Audio Setup, click your sound card name. At least check kX In asio 0 and kX In 1 and 1 kX Out 00 - 2 kX Out 01. In devices, choose the kX ASIO. click ok. On the mixer, on the upper left where it's written Waver under Audio Input 1, click Waver and choose KRISTAL LiveIn. Clcik the first input and choose 1 kX In 00 and for the second choose 2 kX In 01. On the lower right of the mixer, choose kX Out 00 - kX Out 01 for the output. In the first column of the mixer, move the balance bar to the left. In the second column of the mixer, move the balance bar to the right. Now connect a sine wave to asio0 on the epilog like you did to test redocneXk. You should hear the sine wave on the left channel. You can connect the sine wave to asio1 and you will then hear the sine wave on the right channel. If it skips and the cpu is almost idle, there is a problem with the ASIO. On a computer as fast as yours, it should definitely not skip with a big buffer.
